f.lux with Android O

I've been having crashes whenever I to run f.lux with Android O Developer Preview 4. Whenever I enable it, the phone slows to a halt and then eventually reboots.

I know the developer previews are not 100% complete but I was wondering if anyone else has had this issue. DP4 should be mostly final so I'm a little concerned that f.lux might be broken on Android O. Any chance there will be an update to f.lux to fix it?

I'm having the same issue with Android 8.0.0 on a Nexus 5X, build number OPR6.170623.013.

In my case it happens most frequently when trying to wake the phone up from sleep, and it's a soft reboot. The Android logo comes up for a short time, and when the launcher loads f.lux is still running (and colors are still adjusted). Shortly after unlocking the phone I'll get a toast that f.lux is starting and the colors will revert to standard then re-adjust.

i really need a blue tint remover so ive tried some after this problem occured with f.lux, cf lumen had the same problem as f.lux and even in my ex kernel manager app when i reduce the blue color from RGB graphic setting android OS still hang and reboot after a while.
so it might be a android/device side issue...

can any of f.lux support stuff please investigate the issue and tell us what's the source of problem?

@Hamed, I suspect that it's related to the architecture changes in Android from project treble but I'm not certain.

I was able to flash a pixel mod to my 5x that enables night light which seems to work fine. To me that supports the idea that the functionality is there but maybe how it is implemented has changed in Android Oreo. Night light would have been updated for the pixel so it works with Oreo but f.lux hasn't been yet.

Anyways, I tried installing f.lux from the play store, and it is causing some instability with my phone much like @mh0520 has detailed. At first, I wasn't sure if it was due to me rooting my phone, or other rooted apps, but it started when I installed f.lux, and stopped after I toggled the "Disable f.lux" option, so it seems like it's your app :(

It seems like the phone slows down and essentially locks up. It occurs right after a screen wake event, and onset is quite sudden. It is important to note that the screen is still usable, but you cannot see changes well.

e.g. If I hold the power button for a second, my phone will vibrate once and the "Shutdown / Reboot" screen will show. If I try to remember where the "reboot" button is, and where the "yes" button is (when it asks to confirm reboot), the phone will reboot just fine.

I don't see the KCAL driver in cf.lumen when I look in the settings but it does seem to be working okay anyways. In either case, I loaded the Pixel Mod on my phone which enables night light anyways and have been happy with that.

I would still like to see f.lux get fixed but I'm not that concerned at this point.
